where \(P_n (b)\)  is the power consumption of each RIS element which is a function of bit-resolution. We consider 6-bit phase resolution for each RIS element, which consumes \(7.8\)  mW power according to [1]}.
The total power consumption of the amplifying RIS-assisted system is expressed as:
<FIGURE>\(P_\text{tot}^\text{act}=\alpha P_t + P_\text{Tx} + P_\text{Rx} + NP_{n}(b) + \beta \sqrt{P_\text{out}P_\text{max}}\)
